TLDR
In this paper, a series of experiments were performed with rectangular submerged vanes with and without a collar at Froude numbers 0.13 and 0.25, and the decay of vane strength does not follow a similar trend and appears sensitive to the location of center of vortex, Fournet number, etc.Abstract:
For spacing of vane arrays, the information about strength of vortex downstream of a submerged vane is needed. A series of experiments were performed with rectangular submerged vane with and without a collar at Froude numbers 0.13 and 0.25. To define the strength of vortex, a new set of dimensionless parameters using moment of momentum are involved. The present study provides certain information on the decay of strength of vortex with downstream of vane. The decay of vane strength does not follow similar trend and appears sensitive to the location of center of vortex, Froude number, etc. The streamwise spacing of submerged vanes may be taken at least 40H at optimal angle of attack. Centre of vortex is also observed to change with the downstream of submerged vane.read more

TL;DR: In this article, it was shown that short, vertical, submerged vanes installed at incidence to the channel axis in the outer half of a river-bend channel significantly reduce the secondary currents and the attendant undermining and high-velocity attack of the outer bank.

Use of Vanes for Control of Scour at Vertical Wall Abutments
TL;DR: In this paper, the effectiveness of vanes for preventing scour at single-span bridges with vertical wall abutments was evaluated based on laboratory experiments and the results showed that the vanes were highly effective in moving the scour away from the abutment into the center of the channel under all flow conditions tested.
